Condensation of l-menthone with salicylamide followed by isomerization of the adduct withDBU afforded a novel chiral 1, 3-benzoxazinone auxiliary, the usefulness of which was demonstrated by highly diastereoselective aldol reaction with aldehydes.
将1-薄荷酮与水杨酰胺缩合,然后将加合物与DBU异构化,得到了一种新型的手性1,3-苯并恶嗪酮助剂,其有用性通过与醛的高度非对映选择性的醛醇缩合反应得到证明。
